cmon :")

 

I am running the 7.4's and it really isn't that loud man...

 

mine is a definite noticeable sound.. checked rocker bolts too.

 

I am running 7.4's and I can here it. I am going to hold out until I buy a set of heads (looking at TFS) and then measure and change accordingly.

Voted for 7.4's.

Its best to check the preload, depending on how much the heads were milled, and how thick the compressed head gasket. I have used 7.400, and 7.450 and once 7.500.

 

I am using the 7.4s with the t3. I am running the 243 heads and there is some noise.

 

if stock heads I say 7.425. thats just over stock length and will make up mostly for the small base circle the cam was ground on. (assuming here its ground on a smaller basecircle like most comp cams.)

 

I'm running 7.4's with stock heads and the V3 and there is a little noise but its not bad at all....

 

same here.

 

i can hear with window up and definitley window down, should i put pistons at TDC to check the rocker arm bolt torque on all cylindrs? somebody with good knowlege chime in!

 

jon @texas speed told me today that 7.400 are fine..

 

I have used 7.350 with that cam on a stock ls1.

 

7.400 4 me

 

7.400 are fine, but the only way to be completely sure is to use a pushrod length checker.
